AIR-B RAICE C OUPLIN G.

Applicatior filer] To all who'mfit may concern;

Be it known thatJonL H. COLE and JOEL li. COLE, citizens of the UnitedStates, residing lat Arkansas City, in the county'oi Cowley'and State ofKansas, and Winiield, in the county of Cowley and State of Kansas, haveinvented certain new and useful. lmprovements in Air-Brake Couplers, ol"which the following is a speciiication.

This invention relates to railway apparatus, and more .particularly tocouplers for airbrake pipes, and has for an object to proyide. a coupler'capable of automatic locking en gagement with its co-engaging couplerand thus obviate manual assistance.

A further object of this invention is to provide means whereby suchcouplers may be adjusted whereby each coupler may be held in alinementfor eo-engaging its mating coupler.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the invention.

ln the drawings forming a portion ol this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure l is a top plan view of the meeting ends of two railway carsshowing the application of my invention thereto, F ig. 2 is a horizontalsectional view through the couplers, F'g.' 3 is a cross sectional viewon the line 3-3 of Fig. 2, Fig. l is a perspectivev view of one lol" thecouplers, Fig. 5 is a perspeetive view of theattaching member for eachcoupler.

Referring now more particularly to the drawings, there is shown aportion of two cars A. and B respectively. Each ear is provided with. myimproved coupler 10, and as the construction of the members for each earis identical, it is thought that a description of one wil sulilee forboth. Each car is provided with a metallic plate 11 disposed be.- neath4each end of the car adjacent the usual draw-bar, and this plate has itshorizontally disposed portion bolted to the under side oi each ear, asshown at 12. The plate 1.1. is )rm-:ded with longitudinally disposedspaced flanges 13, lor a purpose to be hereinafter described. Aieaf-spring 14 is provided for each plate 1 1 and this spring has aportion ex Specification of Letters Patent.

tending beneath the plate, as shown, and this portion ofthe spring ispivoted for horizontal movement as shown at 15. Each spring outwardly ofthe pivotal point is extended downwardly as shown at 1,6 then curved asa-t 1.7, and then extended upwardly in spaced relation to the portion16, shown at 18. -The spring' at the upper endetl the portion 18 isunderside of the. spring, as shown.

lllaeh coupler 1() consists ol a vertieally exteiiding plate 24/comprising a portion 25 arranged for engagement with the portion 2() ithe spring, and this plate.A has its upper and. lower edges flaredtoward. theportion 25 to provide an enlarged portion 26, and from thisportion the plate is provided with a portion 27 which terminates at itsout-er end to a point 28. The plate 24 is provided upon one side with asocket member 29 comprising vupper and lower walls 30 and 31respectively and a connecting side wall The socket member is providedwith an enlarged Outer end 33, and at the inner end the member isreduced as shown at .34. The outer edge of each wall of the socketmember beveled as shown at The lsocket member is preferably located withits inner end adja-v cent the portion 25 of the plate 24', and with itsother portion adjacent theouter end of the enlargement 26. Upon theplate 24 opposite the socket member 4there is.

provided. a socket engaging member 36 oonsist-ing olahorizontally'disposed plate 37 which has its outer edge tapered to apoint 3N The plate 37 is provided with longitudinally disposed wearstrips 3) and 4() located upon the upper and lower side ol the pl ate 37at the outer edge thereof'. The plate 37 is tapered at its outer edge asshown l'or en gage ment with the. side wall 32 ol" its cri-engagingsocket. Each plate 24 is provided with an inwardly directed nipple 41for attachment of the train, line hose 42. The nipple 41 has y1 ooother, pivoted springsfor yieldingly its inner end disposed in ahorizontal passage 43 in the plate 24 and at the opposite side of theplate from the nipple, lthe passage is enlarged as shown at44, and isthus arranged to receive a rubber washer 45, i

It will of course be understood that each coupler for the ends ofadjoining ears is arranged with its vparts oppositely disposed, that isto say the coupling member of one car will be arranged to engage. thesocket of its co-engaging coupler. i y

.By use of a coupler of this character it will De seen that if anattempt should be made to uncouple the cars while the train is in motionthe springs would immediately return each member of the coupler to itsoriginal position, and thus iobviate trainmen re-coupling the memberswhich would of c'ourse result in delay of the train. The use of thesprings serves to provide a coupler which will be operable at all times,and by the provision of the adjusting screws for each spring it will beseen that each coupler may accurately set for co-engagement with eachother.

What is-claimed is:

1. A coupler of the class described comrising coengaging members, each'meinberiaving oppositely disposed sockets, means carried by each memberfor engagement-in the sockets, air line connections carried by eachmember and communicating with each supporty seaoee ing said members, andadjusting scre -s engaged 'with said springs.

2. .A coupler ol" tl'ie class prising co engaging coupling member'-springs carried by said members,A attaching plates, and adjusting screwscarried by said plates and engaged with said springs. v

3. The combination with a car, of a plate carried thereby, a springpivotally mounted upon the under side of said late, and air brakecoupling section carried by said spring, and screws carried by saidplate and engaged with the spring for movement of the coupling sectionin a horizontatplane.

4. The combination with a ca r, of a plate carried thereby, a springpiyotally connected. With the under side of the plate, a coupling membercarried by said sl'iring, a socket member carried by said couplingmember, air line connections carried by said member, a socket-engagingmember carried by said coupling member and located outwardly bf thesocket member, and means carried by described comY said plate foradjusting said spring in a liori zontal plane.

In testimony whereof we ailix our .signa tures, in presenceof twoWitnesses.
